I emailed white2tea about how to store their oolong that has been pressed into bricks. I've had a handful of sour teas over the last year or so, and I'm thinking about it a lot whenever I open an oolong. The white2tea oolong ofc doesn't come in a vacuum sealed bag. I realized after this exchange that I should probably drink this tea right away before opening or buying any more oolong.
Me: How do you store bricks of oolong?
Him: Personally, I would keep them the same way as raw Puer, but it depends on your storage/goals. If you like you could also keep them very dry and sealed to maintain more aroma, whereas I’d prefer to have them more smooth over time.
Me: Ok. You don't worry about this tea becoming sour?
Him: Most any question like that will depend greatly on a lot of factors like your goals/location/preferences. Aging tea can have a lot of out comes.
